What's an Override?
Using Overrides
An override is a feature for adjusting the feed rate or spindle speed while cutting is in progress. This is useful when you want
to change the feed rate or speed as you monitor the status of cutting.
An override value is specified as a percentage. For example, when the command in the cutting data sent from the computer
is for a speed of 5,000 rpm, specifying an override of 150% produces an actual speed of 7,500 rpm.
Types of Overrides
There are three types of overrides, and you can make the settings for each one separately.
Feed-rate Override
This is the speed at which the tool moves when cutting the workpiece. The speed specified by the command in the cutting
data is taken to be 100%.
Rapid-feed Override
This is the speed at which the tool moves during no-load feed. The maximum speed of the machine is taken to be 100%.
Spindle Override
This is the speed of spindle rotation. The speed specified by the command in the cutting data is taken to be 100%. This is
also effective when rotating the spindle during manual operations.
How to Make the Settings for Overrides
Important Notes on Overrides
Setting an override does not let you perform operation beyond the machine's maximum or minimum speeds.
Depending on the program, the rapid-feed override may have no effect, or the feed-rate override may alter the speed
of the rapid-feed override.
Operation Using the Handy Panel
You can also perform this operation using the handy panel.
Clicking these buttons
adjusts the values.
